Enoch, like Melchizedek appears briefly in Genesis and then does not reappear in the Protestant canon until "To the Hebrews". While less is said in Hebrews about Enoch than about Melchizedek much is written of Enoch in extra-biblical writings.
However, "the scrolls of Enoch" was an early apocalypse that was popular with Jews and Christians alike but not included in the Catholic or Protestant canons. It was quoted by NT writers and seems to have influenced many NT passages.
I'm too lazy to give an exhaustive report on the place of Enoch in this answer but I will point out that he was clearly understood to not have died and to have been transported directly into the sky, to where God and the angels are. In addition he is taken on a tour of the place of the dead and the prison of angels.
He also appears to be equated with Philo's logos and the messenger that accompanied Moses on the Exodus.

The one thing I do want to call attention to that is particularly relevant to the question at hand is Peter's cryptic reference to Enoch's preaching to the angels in prison in which he seems to be identifying Christ with Enoch!:
NIV 1 Peter 3: 18For Christ also suffered once for sins, the righteous
for the unrighteous, to bring you to God. He was put to death in the
body but made alive in the Spirit. 19After being made alive, he
went and made proclamation to the imprisoned spirits— 20to those who
were disobedient long ago when God waited patiently in the days of
Noah while the ark was being built. In it only a few people, eight
in all, were saved through water,
This is a clear reference to the scrolls of Enoch:
[Chapter 15] 1 And He answered and said to me, and I heard His voice:
'Fear not, Enoch, thou righteous 2 man and scribe of righteousness:
approach hither and hear my voice. And go, say to the Watchers of
heaven, who have sent thee to intercede for them: "You should
intercede" for men, and not men 3 for you: Wherefore have ye left the
high, holy, and eternal heaven, and lain with women, and defiled
yourselves with the daughters of men and taken to yourselves wives,
and done like the children 4 of earth, and begotten giants (as your)
sons? And though ye were holy, spiritual, living the eternal life, you
have defiled yourselves with the blood of women, and have begotten
(children) with the blood of flesh, and, as the children of men, have
lusted after flesh and blood as those also do who die 5 and perish.
Therefore have I given them wives also that they might impregnate
them, and beget 6 children by them, that thus nothing might be wanting
to them on earth. But you were formerly 7 spiritual, living the
eternal life, and immortal for all generations of the world. And
therefore I have not appointed wives for you; for as for the spiritual
ones of the heaven, in heaven is their dwelling. 8 And now, the
giants, who are produced from the spirits and flesh, shall be called
evil spirits upon 9 the earth, and on the earth shall be their
dwelling. Evil spirits have proceeded from their bodies; because they
are born from men and from the holy Watchers is their beginning and
primal origin; 10 they shall be evil spirits on earth, and evil
spirits shall they be called. [As for the spirits of heaven, in heaven
shall be their dwelling, but as for the spirits of the earth which
were born upon the earth, on the earth shall be their dwelling.] And
the spirits of the giants afflict, oppress, destroy, attack, do
battle, and work destruction on the earth, and cause trouble: they
take no food, but nevertheless 12 hunger and thirst, and cause
offences. And these spirits shall rise up against the children of men
and against the women, because they have proceeded from them.
[Chapter 16] 1 From the days of the slaughter and destruction and
death of the giants, from the souls of whose flesh the spirits, having
gone forth, shall destroy without incurring judgement -thus shall they
destroy until the day of the consummation, the great judgement in
which the age shall be 2 consummated, over the Watchers and the
godless, yea, shall be wholly consummated." And now as to the watchers
who have sent thee to intercede for them, who had been aforetime in
heaven, (say 3 to them): "You have been in heaven, but all the
mysteries had not yet been revealed to you, and you knew worthless
ones, and these in the hardness of your hearts you have made known to
the women, and through these mysteries women and men work much evil on
earth." 4 Say to them therefore: " You have no peace."'
[Chapter 21] ...Then I said: 'How 9 fearful is the place and how
terrible to look upon!' Then Uriel answered me, one of the holy angels
who was with me, and said unto me: 'Enoch, why hast thou such fear and
affright?' And 10 I answered: 'Because of this fearful place, and
because of the spectacle of the pain.' And he said unto me: 'This
place is the prison of the angels, and here they will be imprisoned
So I see every reason to believe that Hebrews, as well as Peter to have understood Enoch to have been transported to "heaven" and "descended into hell" and preached to the angels in Tartarus, the prison of angels, in the days of Noah.
